Hi @dhaval,
Welcome to the Bunnings Workshop community, it is fantastic to have you with us.
Can you advise what the pink stain is from? Also, what kind of flooring do you have? Is it actual timber, or timber-look laminate or vinyl flooring?
Knowing what the stain is from and the type of flooring will help to guide the approach.
Without knowing these things, I can only recommend generic solutions such as scrubbing it with a medium-stiffness brush like this Oates Soft Grip Scrub Brush and a neutral floor cleaner such as this Peerless JAL Versadet Neutral Floor Cleaner.
If you can provide further details, there may be a more tailored solution, but I would be worried that they would damage your floor further without knowing what we are dealing with.
I will assist further when you can get back to me.
Jacob
